3. Press the M button to select the unit of measure symbol F.
4. Touch the test probe tips across the part under test.
5. Use the Relative mode to compare measurements to a saved, known capacitance value.
See the dedicated Relative mode instructions in this user guide for more detail.
6. Read the capacitance value in the display (bargraph is not available in capacitance mode).
7. The display will indicate the proper decimal point and value.
